The stages of the plot in order are exposition, rising action, conflict, climax, and resolution. Usually, the climax is the highest point of interest in a story because it is the most intense. It reveals everything the reader has been questioning and usually results in some sort of battle or conflict with the antagonist. The exposition and rising action are the main part of the story that leads up to the conflict and climax. After the climax comes the falling action and resolution which resolves the stories problems and ends the story. I would go with answer A. Climax.
B, you need to give the reader basically a reason to read it so you give the hook and the topic of the sentence so basically what the story is going to be about.
